Nipsey Hussle's suspected killer, Eric Holder, is being held in solitary confinement, TMZ reports today (April 3).

According to the celebrity news site, police fear for the 29-year-old Los Angeles man's life, so that's why he's in solitary, a place he will reportedly be for a long time. On an additional note, Holder has reportedly just had his bail set at $7,040,000.

Nipsey Hussle was shot and killed on Sunday (March 31), and police quickly identified Holder as the primary suspect. Speaking at a press conference yesterday, Los Angeles Police Department Chief Michel Moore explained the LAPD's belief that Nipsey's death was the result of a personal dispute between Holder and Nipsey rather than a gang-related matter.

"At this point of our investigation based on witness statements and the background of those that we've identified, we believe this to be a dispute between Mr. Hussle and Mr. Holder," Moore said at the conference. "I'm not going to go over the conversation, but it appears to be a personal matter between the two."

Yesterday (April 2), Holder was arrested for allegedly shooting Hussle.
